Scalable Ultra-High Throughput JPEG-LS Encoder
JPEG-LS is based on the LOCO-I (Low Complexity-Lossless Compression for Images) image compression algorithm, which uses a non-linear predictive scheme with rudimentary edge detecting capability, based on the four nearest –causal- neighbours (left, upper left, upper and upper right) and an entropy encoder using adaptively selective Golomb-type codes. The low complexity scheme of JPEG-LS is based on the assumption that prediction residuals follow a two-sided geometric distribution and the fact that Golomb-codes are optimal for geometric distributions, thus the modeling and coding units are matching.
